Specification of Letters Patent.

Patented June 30, 1908.

Application filed March 19, 1908. Serial No. 422,051.

T 0 all whom it may concern:

Be it known that I, THOMAS B. GARRET- SON, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and invented a new and useful Adjustable Stilt, of which the following is a specification.

This invention relates to. walking stilts,

'andhas for its object to provide a simple and inexpensive means for vertical adjustment of the foot piece to any required height on the pole or support. \Vith most devices of this kind now in use, a number of parts are employed in order to render the foot piece adjustable, and it frequently happens that when one or more of these parts are lost, the stilt is rendered useless, unless the part is replaced by a new one, which frequently involves considerable expense. The present invention aims to remedy this defect by so constructing the device as to render loss of the parts practically impossible, and, at the same time, greatly decreases the number of parts usually employed in constructing devices of this kind.

With these and other objects in view, as

. will more fully hereinafter a ppcar, the invcntionconsists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, pro portions, size and minor details of the structlfl'fl may be made without departing from the spirit 'or sacrificing any of the advantagesof the invention.

in, theaccompanying drawings:-Figure 1 is a side elevation, partly 1n section, d1sclosing the arrangement for holding the foot piece in ad usted position. Fig. 2 1s a plan view of the foot piece, showing the engaging groove. Fig. 3 is a vertical section taken through the socket disclosing the engaging groove.

Similar numerals of reference are employed to indicate correspomhng parts throughout the several figures of the draw ings.

The starulard 1', preferably formed of wood or other suitable material, is provided on one face with a series of suitably spaced perforations for the reception of a wood screw or pin 2, the head 3 of which is rounded for a purpose to be presently described]; 'lhestcp is preferably formed of metal cast in one piece, and provided at one end with a socket 4 of a size sullicient to embrace the standard 1. The arm or step proper 5 extends outwardly and at a )PXOXllIHUZOlY right angles to the walls of the socket 4, the upper face of the step lying in a plane with the upper edges of the socket walls, and at the lower face being provided with a web of increasing thickness from the outer end of the ste to the socket 4. ()n the side wall of the soc et adjacent the step 5 is formed a longitudinal groove 7 eX- tending the entire length of the wall. The walls of the groove 7 converge from the base of the socket to the upper end thereof, so that when the screw 2 is in position in one of the perforations formed in the standard 1, and the head 3 flat against the outer face thereof, by forcing the step downward on the standard, the walls of the groove come in contact with the round head 3 of the screw 2 which makes further downward movement of the step impossible.

In order to adjust the step, the operation is simply reversed, the screw removed" and inserted in another of the perforations,ieither higher or lower on the standard, as desired.

lVhat is claimed is:---- I 1. ln a walking stilt, the combination fwith a standard having spaced openings, ofia foot iece having a socket on one end, a groove formed in the wall of the socket, and a member removably secured in-thc openings'of the standardfor engagement with the walls of the groove. F

2. In a walking stilt, the combination with a standard, of a foot piece having a; socket adapted to embrace said standard, agroove having converging sides formed on o ne wall ofsaid socket, and a screw in the standard for engagement with the sides of said groove.

In testimony that I claim the foregoing as my own, I have hereto allixcd my signature in the presence of two witnesses.
